CONSTRUCTION OF PRlVY-VAULTS AND APPARATUS FOR USE THEREWlTH.

SPECIFICATION forming part of Letters Patent No. 335,177, dated February2 1886.

Application filed August 525, 1884. Serial No. 141,434. (No model.)

cleanliness in and around privy-vaults and to prevent accumulationstherein, especially in localities where water is not easily available;and to those ends my invention consists in the construction and in thearrangements hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figurelis a vertical cross-section of a vault and building of theimproved construction. Fig. 2 is a section lengthwise of the vault onthe line w x in Fig. 3. Fig. 3 is a sectional plan view above ground.Fig. 4 is a section, in larger size, of the hopper and receptacle. Fig.5 is a side view of the hopper. Figs. 6, 7, and 8 are detail views.

The vault A is to be of any suitable length and width, according to thenumber of receptacles it is to contain, and is to be in length abouttwice the width and of such depth that the top of the receptacle usedwill be near the surface of the ground. The walls and bottom of thevault are formed of concrete, so as to be proof against the absorptionof liquid, and the inside may be covered with cement.

Over the vault is constructed the building, but its floor covers onlyone half of the vault, and the back wall, a, is set into the floor, sothat the vault is accessible from the outside. The roof extends over theoutside portion of the vault,and a slanting cover is provided at b toexclude rain. WVithin the building are seats a, to which the hoppers dare attached by means of flanges 6, so that the hoppers are suspended.The hoppers,as shown most clearly in Figs. 4 and 5, have tubularextensions f, that are fitted with telescopic outer tubes, 9, held by abayonet-catch, so that they can be raised and lowered when a receptacleis put in place or one removed, and handles it are fitted on tubes g foruse in moving them.

The receptacles B are tight barrels, having openings in their heads toreceive the tube 9 snugly; and for closing the openings I provide theplates k, that have packings at i to fit around the openings in thebarrels. On the heads, as shown in Fig. 8, there are screwpins t, whichpass through the covering-plates h, and have nuts for clamping thecovers down tightly. The barrels are also provided with handles h Theseats 0 are provided with covers Z,fitting closely, and from the sidesof hoppers d pipes at pass upward and through the roof of the buildingfor ventilating the receptacles and to prevent accumulation of gases.

Above the outside part of the vault A, I provide a fall, a, which-is tobe used to draw up the barrels when filled and to lower empty ones. Thebarrels rest on small wheeled trucks 0, so that they can be readilymoved into the position for connection with the hoppers and also movedout for being raised.

With these arrangements the vault can be kept in a cleanly condition atall times, and there will be no exposure of excrement to the air in thevault. The air will not be tainted by unhealthy odors, neither can therebe any escape of liquids into the ground in case the barrels overflow.

The covering-plates h will be attached to the barrels by chains, so asto be at hand when required.

The vault is to be larger or smaller, according to the numberof barrelsto be used in it,and it may be ventilated by a pipe passing upwardthrough the house.

The vault and the coverings for the receptacle herein described form nopart of the present invention.

I am aware that it is old to provide sections of pipe, &c., with abayonet-fastening, and I therefore disclaim the broad idea of suchfastening; but I am not aware that a hopper of the character describedhas been provided with such a fastening in this particular connection,and as it is desirable when changing the barrels underneath the hopperto have the neck of the hopper suspended out of the way of the top ofthe barrel and to have it remain in place while the removal of barrelstakes place, I provide this L-shaped bayonet-fastening, whereby, bygiving the sleeve a partial rotation,it will be held in position by thelug on the lower portion of the hopper. Again, as these pipes, from thenature of the case, are quite liable to become covered with a dampcoating of slime and impure moisture, it is very desirable to have themso constructed that they will be easily and readily operated and at thesame time be practically tight. To facilitate this operation, then, Iprovide the handles on each side of the sleeve, which afford a means ofgrasping and holding the sleeve with very little liability of soilingthe hands,as well as enabling the operator to move a tightly-fittingsleeve, which, were it not for the handles,might be practicallyimmovable.

' What I claim as new is In a dry privy-vault for outhouses, a seat anda hopper suspended therefrom and provided with alug, in combination witha barrel and a sleeve telescopically secured over the lower portionofthe hopper and provided with an L- shaped slot, which fits over andsurrounds the lug on' the hopper, and also having handles on the outsideof the sleeve, all constructed and combined to operate substantially asdescribed, whereby the sleeve may be raised or lowered as the barrelsare removed and replaced, sub stantially as set forth.
